主要包括以下四点： 频域变换：傅里叶变换和离散余弦变换及其反变换，可将图像在空域上的特性转化到频域上； 叠加噪声：对图像添加高斯噪声和椒盐噪声； 空域滤波：对噪声污染后的图像添加不同模板下的平滑滤波和锐化滤波，可选择不同模板尺寸； 频域滤波：对噪声污染后的图像添加理想低通滤波器、巴特沃斯低通滤波器、理想高通滤波器、巴特沃斯高通滤波器、带通滤波器、带阻滤波器等，可实现平滑图像的效果。
function varargout = untitled2(varargin)
% UNTITLED2 M-file for untitled2.fig
% UNTITLED2, by itself, creates a new UNTITLED2 or raises the existing
% singleton*.
%
% H = UNTITLED2 returns the handle to a new UNTITLED2 or the handle to
% the existing singleton*.
%
% UNTITLED2(‘CALLBACK‘,hObject,eventData,handles,...) calls the local
% function named CALLBACK in UNTITLED2.M with the given input arguments.
%
% UNTITLED2(‘Property‘,‘Value‘,...) creates a new UNTITLED2 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before untitled2_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to untitled2_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE‘s Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
